> Expired SampleStat should ignore when generating SlowPeersReport

> SlowPeersReport is generated by the SampleStat between tow dn, so it can
> present on nn's jmx like this:
> {code:java}
> "SlowPeersReport" :[{"SlowNode":"dn2","ReportingNodes":["dn1"]}]
> {code}
> In each period, MutableRollingAverages will do a rollOverAvgs(), it will
> generate a SumAndCount object which is based on SampleStat, and store it in a
> LinkedBlockingDeque<SumAndCount>, the deque will be used to generate
> SlowPeersReport. And the old member of deque won't be removed until the queue
> is full. However, if dn1 don't send any packet to dn2 in the last of
> 36*300_000 ms, the deque will be filled with an old member, because the
> number of last SampleStat never change.I think these old SampleStats should
> be considered as expired message and ignore them when generating a new
> SlowPeersReport.
